DETAILED DESCRIPTION

First, some concepts and general operation manners involved in implementation of the disclosure will be briefly explained.

The 5th-generation of mobile communication technology (5G) new radio (NR) is a newly proposed topic in the 3rd generation partnership project (3GPP) organization. As the discussion of the new generation of 5G technology gradually deepens, on the one hand, because the communication system is backward compatible, the new technology developed later tends to be compatible with the previously standardized technology; on the other hand, because the 4G LTE system already proposes a large number of existing solutions, in order to achieve compatibility, it has to sacrifice a lot of flexibility of 5G to reduce performance. Therefore, there are currently two parallel studies in the 3GPP organization, the backward-compatible is not considered by one of the technical discussion groups, which is called 5G NR.

Currently, in the research process of the 5G NR system, for a terminal that does not support simultaneous transmission of PUCCH and PUSCH, when the terminal needs to simultaneously transmit the uplink control information (UCI) and PUSCH in one subframe, the UCI needs to be transmitted through the PUSCH. For periodic UCI information, the base station and the terminal can accurately predict the capacity and transmission time of the feedback information, so that reasonable resource scheduling can be performed to ensure the transmission performance of the PUSCH and the UCI. However, for acknowledgment/non-acknowledgment (ACK/NACK) information, since the NR supports flexible scheduling/HARQ timing, the base station cannot accurately predict the ACK/NACK feedback when transmitting the uplink grant UL grant (PUCCH). As shown in FIG. 1, the terminal receives the first downlink control information (DCI) in the time unit n, the first DCI being used for scheduling terminal to transmit the PUSCH in the time unit n+k; the terminal receives the second downlink control information in the time unit m1, the first feedback response information corresponding to the second downlink control information is transmitted in the time unit n+k; and the terminal receives the third downlink control information in the time unit m2, the second feedback response information corresponding to the third downlink control information is transmitted in the time unit n+k. Since the base station supports flexible scheduling/HARQ timing, the base station cannot accurately predict the feedback situation such as the number of the first feedback response information and the number of the second feedback response information, and thus cannot implement accurate scheduling. In this case, there is no clear solution on how to achieve efficient UCI multiplexing transmission.

As to the above problem, implementation of the present disclosure provides an information transmission method and related products. The method includes following actions. The terminal firstly receives the first DCI, which is used for scheduling the terminal to transmit uplink data through PUSCH in the target time unit; secondly, receives the second DCI, feedback response information of which is transmitted in the target time unit, and transmission time of which is before or the same as the target time unit; and finally determines, according to the transmission time of the second DCI, that the feedback response information of the second DCI is transmitted through PUSCH in the target time unit. The transmission time of the second DCI can be used for determining the feedback response information and the PUSCH multiplex transmission, so as to accurately multiplex and transmit the feedback response information through the PUSCH, thereby avoiding such a situation that the network device cannot perform accurate data scheduling as being unable to accurately identify information (such as number) of the feedback response information, and improving the accuracy and stability of data scheduling in the communication system.

The technical solutions in the implementation of the disclosure will be described below with reference to the accompanying drawings.

Please refer to FIG. 1. FIG. 1 is an exemplary network architecture diagram of a communication system according to an implementation of the disclosure. The exemplary communication system can be, for example, a 5G NR system and other such communication systems. The exemplary communication system specifically includes a network device and a terminal. When the terminal accesses the mobile communication network provided by the network device, the terminal and the network device can be communication connected by using a wireless link, and the communication connection may be in a single connection mode, a dual connection mode, or a multiple connection mode. When the communication connection is in the single connection mode, the network device may be an LTE base station or an NR base station (also referred to as a gNB base station). When the communication connection is in the dual connection mode, which may be specifically implemented by carrier aggregation (CA) technology or by a plurality of network devices, and the terminal is connected to multiple network devices, the multiple network devices may include a master cell group (MCG) and a secondary cell group (SCG), and the base stations may perform data backhaul through the backhaul link. The MCG may include an LTE base station, and the SCG may include an LTE base station. Alternatively, the MCG may include an NR base station, and the SCG may include an LTE base station. Alternatively, the MCG may include an NR base station, and the SCG may include an NR base station.

In the implementation of the disclosure, the terms “network” and “system” are often used interchangeably, and those skilled in the art can understand the meaning thereof. The terminals involved in the implementation of the disclosure may include various handheld devices, in-vehicle devices, wearable devices, computing devices, or other processing devices connected to the wireless modem, and various forms of user equipment (UE), mobile station (MS), terminal device, and the like. For convenience of description, the devices mentioned above are collectively referred to as the terminal.

Referring to FIG. 2, FIG. 2 illustrates an information transmission method according to an implementation of the disclosure, which is applied to the foregoing exemplary communication system, and the method includes following actions.

In block 201, the terminal receives a first downlink control information (DCI), the first DCI being used for scheduling the terminal to transmit uplink data in a target time unit through a physical uplink shared channel (PUSCH).

In an implementation, the time unit may be a time domain transmission unit such as a subframe, a time slot, or a symbol.

In block 202, the terminal receives a second DCI, feedback response information of the second DCI being transmitted in the target time unit, and transmission time of the second DCI being before the target time unit or the same as the target time unit.

In block 203, the terminal determines, according to the transmission time of the second DCI, to transmit the feedback response information of the second DCI through the PUSCH in the target time unit.

It can be seen that, in this implementation of the disclosure, the terminal firstly receives the first DCI, which is used for scheduling the terminal to transmit uplink data through PUSCH in the target time unit; secondly, receives the second DCI, feedback response information of which is transmitted in the target time unit, and transmission time of which is before or the same as the target time unit; and finally determines, according to the transmission time of the second DCI, that the feedback response information of the second DCI is transmitted through PUSCH in the target time unit. The transmission time of the second DCI can be used for determining the feedback response information and the PUSCH multiplex transmission, so as to accurately multiplex and transmit the feedback response information through the PUSCH, thereby avoiding such a situation that the network device cannot perform accurate data scheduling as being unable to accurately identify information (such as number) of the feedback response information, and improving the accuracy and stability of data scheduling in the communication system.

In a possible example, the determining, by the terminal according to the transmission time of the second DCI, to transmit the feedback response information of the second DCI through the PUSCH in the target time unit includes: determining, by the terminal, that the transmission time of the second DCI is before or the same as the transmission time of the first DCI; performing, by the terminal, rate matching on the uplink data scheduled by the first DCI according to a number of bits of the feedback response information of the second DCI or resource occupied by the feedback response information of the second DCI; and transmitting, by the terminal through the PUSCH, the feedback response information of the second DCI and the uplink data being rate matched.

In an implementation, the rate matching refers to determining the number of bits after data encoding according to the number of bits of the UCI or the number of resource occupied by the UCI.

It can be seen that in this example, the network device can accurately predict the number of bits of the coded data after the rate matching, so that the data scheduling can be accurately performed, such as selecting the appropriate resource number and modulation code level.

In a possible example, the determining, by the terminal according to the transmission time of the second DCI, to transmit the feedback response information of the second DCI through the PUSCH in the target time unit includes: determining, by the terminal, that the transmission time of the second DCI is after the transmission time of the first DCI; and multiplexing, by the terminal, the feedback response information of the second DCI into the PUSCH in a puncturing manner for transmission.

In an implementation, the puncturing manner refers to mapping the encoded data to the entire PUSCH resource. After determining the physical resource occupied by the UCI, the terminal may directly puncture the data symbols to be transmitted and replaces them with UCI symbols. When the number of UCI information is large, continuously deleting a large number of data symbols may affect the data demodulation performance.

It can be seen that, in this example, the network device does not reserve resource for the feedback response information, and uses the puncturing manner to perform multiplexing transmission when the feedback response information occurs, so as to avoid waste of resource.

In a possible example, the second DCI includes a plurality of DCIs, each DCI has feedback response information; and the determining, by the terminal according to the transmission time of the second DCI, to transmit the feedback response information of the second DCI through the PUSCH in the target time unit includes: determining, by the terminal, that a transmission time of at least one of the plurality of DCIs is after the transmission time of the first DCI; and multiplexing, by the terminal, the feedback response information of the plurality of DCIs into the PUSCH in a puncturing manner for transmission.

It can be seen that, in this example, when transmission time of any one of the multiple DCIs is after the transmission time of the first DCI, all the feedback response information is uniformly processed to avoid increasing implementation complexity caused by using different multiplexing manners for different feedback response information.

In a possible example, the determining, by the terminal according to the transmission time of the second DCI, to transmit the feedback response information of the second DCI through the PUSCH in the target time unit includes: determining, by the terminal, a time interval between the transmission time of the second DCI and the target time unit or between the transmission time of the second DCI and a starting position of the PUSCH; and determining, by the terminal according to the time interval, to transmit the feedback response information of the second DCI through the PUSCH in the target time unit.

In this possible example, the determining, by the terminal according to the time interval, to transmit the feedback response information of the second DCI through the PUSCH in the target time unit includes: determining, by the terminal, that the time interval is not less than a preset time interval, performing rate matching on the uplink data scheduled by the first DCI according to a number of bits of the feedback response information of the second DCI or resource occupied by the feedback response information of the second DCI; and transmitting, by the terminal through the PUSCH, the feedback response information of the second DCI and the uplink data being rate matched.

In an implementation, the value of the preset time interval is determined by a preset protocol, or the value of the preset time interval is configured by the network device, and is not limited herein. The preset time interval is a minimum processing delay of the uplink scheduling supported by the terminal.

It can be seen that, in this example, when the time interval is not less than the preset time interval, the network device can accurately predict the number of bits of the coded data after the rate matching, so that the data scheduling can be accurately performed, such as selecting the appropriate resource number and modulation code level.

In this possible example, the determining, by the terminal according to the time interval, to transmit the feedback response information of the second DCI through the PUSCH in the target time unit includes: determining, by the terminal, that the time interval is less than a preset time interval, and multiplexing the feedback response information of the second DCI into the PUSCH in a puncturing manner for transmission.

It can be seen that, in this example, when the time interval is less than the preset time interval, the terminal cannot complete the rate matching processing on the data according to the number of the feedback response information or the resource occupied by the feedback response information, and therefore needs to perform the puncturing process, which is beneficial to improve stability and real-time performance of the scheduling.

In a possible example, the second DCI includes a plurality of DCIs, each DCI has feedback response information; and the determining, by the terminal according to the transmission time of the second DCI, to transmit the feedback response information of the second DCI through the PUSCH in the target time unit includes: determining, by the terminal, that a time interval between a transmission time of at least one of the plurality of DCIs and the target time unit or between the transmission time of at least one of the plurality of DCIs and a starting position of the PUSCH is less than a preset time interval; and multiplexing, by the terminal, the feedback response information of the plurality of DCIs into the PUSCH in a puncturing manner for transmission.

It can be seen that, in this example, when transmission time of any one of the multiple DCIs is after the transmission time of the first DCI, all the feedback response information is uniformly processed to avoid increasing implementation complexity caused by using different multiplexing manners for different feedback response information.

In a possible example, the method further includes: transmitting, by the terminal, the preset time interval to a network device; or transmitting, by the terminal, information of terminal capability to the network device, the information of terminal capability including the preset time interval.

In accordance with the implementation as shown in FIG. 2, now referring to FIG. 3, which illustrates an information transmission method according to an implementation of the disclosure. The method is applied to the foregoing exemplary communication system and includes following actions.

In block 301, the network device transmits a first downlink control information (DCI), the first DCI being used for scheduling a terminal to transmit uplink data in a target time unit through a physical uplink shared channel (PUSCH).

In block 302, the network device transmits a second DCI, feedback response information of the second DCI being transmitted in the target time unit, and transmission time of the second DCI being before the target time unit or the same as the target time unit.

In block 303, the network device determines, according to the transmission time of the second DCI, to receive the feedback response information of the second DCI through the PUSCH in the target time unit.

It can be seen that, in this implementation of the disclosure, the network firstly transmits the first DCI, which is used for scheduling the terminal to transmit uplink data through PUSCH in the target time unit; secondly, transmits the second DCI, feedback response information of which is transmitted in the target time unit, and transmission time of which is before or the same as the target time unit; and finally determines, according to the transmission time of the second DCI, to receive the feedback response information of the second DCI through PUSCH in the target time unit. The transmission time of the second DCI can be used for determining the feedback response information and the PUSCH multiplex transmission, so as to accurately multiplex and transmit the feedback response information through the PUSCH, thereby avoiding such a situation that the network device cannot perform accurate data scheduling as being unable to accurately identify information (such as number) of the feedback response information, and improving the accuracy and stability of data scheduling in the communication system.

In a possible example, the determining, by the network device according to the transmission time of the second DCI, to receive the feedback response information of the second DCI through the PUSCH in the target time unit includes: determining, by the network device, that the transmission time of the second DCI is after or the same as the transmission time of the first DCI; performing, by the network device, rate de-matching on the uplink data scheduled by the first DCI according to a number of bits of the feedback response information of the second DCI or resource occupied by the feedback response information of the second DCI; and demodulating, by the network device, the uplink data and the feedback response information of the second DCI.

It can be seen that in this example, the network device can accurately predict the number of bits of the coded data after the rate matching, so that the data scheduling can be accurately performed, such as selecting the appropriate resource number and modulation code level.

In a possible example, the determining, by the network device according to the transmission time of the second DCI, to receive the feedback response information of the second DCI through the PUSCH in the target time unit includes: determining, by the network device, that the transmission time of the second DCI is after the transmission time of the first DCI; determining, by the network device, that the feedback response information of the second DCI is multiplexed into the PUSCH in a puncturing manner for transmission; and demodulating, by the network device, the uplink data and the feedback response information of the second DCI.

It can be seen that, in this example, the network device does not reserve resource for the feedback response information, and uses the puncturing manner to perform multiplexing transmission when the feedback response information occurs, so as to avoid waste of resource.

In a possible example, the second DCI includes a plurality of DCIs, each DCI having feedback response information; and the determining, by the network device according to the transmission time of the second DCI, to receive the feedback response information of the second DCI through the PUSCH in the target time unit includes: determining, by the network device, that a transmission time of at least one of the plurality of DCIs is after the transmission time of the first DCI; determining, by the network device, that the feedback response information of the plurality of DCIs is multiplexed into the PUSCH in a puncturing manner for transmission; and demodulating, by the network device, the uplink data and the feedback response information of the plurality of DCIs.

It can be seen that, in this example, when transmission time of any one of the multiple DCIs is after the transmission time of the first DCI, all the feedback response information is uniformly processed to avoid increasing implementation complexity caused by using different multiplexing manners for different feedback response information.

In a possible example, the determining, by the network device according to the transmission time of the second DCI, to receive the feedback response information of the second DCI through the PUSCH in the target time unit includes: determining, by the network device, a time interval between the transmission time of the second DCI and the target time unit or between the transmission time of the second DCI and a starting position of the PUSCH; and determining, by the network device according to the time interval, to receive the feedback response information of the second DCI through the PUSCH in the target time unit.

In the possible example, the determining, by the network device according to the time interval, to receive the feedback response information of the second DCI through the PUSCH in the target time unit includes: determining, by the network device, that the time interval is not less than a preset time interval, performing rate de-matching on the uplink data scheduled by the first DCI according to a number of bits of the feedback response information of the second DCI or resource occupied by the feedback response information of the second DCI; and demodulating, by the network device, the uplink data and the feedback response information of the second DCI.

It can be seen that, in this example, when the time interval is not less than the preset time interval, the network device can accurately predict the number of bits of the coded data after the rate matching, so that the data scheduling can be accurately performed, such as selecting the appropriate resource number and modulation code level.

In the possible example, the determining, by the network device according to the time interval, to receive the feedback response information of the second DCI through the PUSCH in the target time unit includes: determining, by the network device, that the time interval is less than a preset time interval, and determining that the feedback response information of the second DCI is multiplexed into the PUSCH in a puncturing manner for transmission; and demodulating, by the network device, the uplink data and the feedback response information of the second DCI.

It can be seen that, in this example, when the time interval is less than the preset time interval, the terminal cannot complete the rate matching processing on the data according to the number of the feedback response information or the resource occupied by the feedback response information, and therefore needs to perform the puncturing process, which is beneficial to improve stability and real-time performance of the scheduling.

In a possible example, the second DCI includes a plurality of DCIs, each DCI having feedback response information; the determining, by the network device according to the transmission time of the second DCI, to transmit the feedback response information of the second DCI through the PUSCH in the target time unit includes: determining, by the network device, that a time interval between a transmission time of at least one of the plurality of DCIs and the target time unit or between the transmission time of at least one of the plurality of DCIs and a starting position of the PUSCH is less than a preset time interval; determining, by the network device, that the feedback response information of the plurality of DCIs is multiplexed into the PUSCH in a puncturing manner for transmission; and demodulating, by the network device, the uplink data and the feedback response information of the plurality of DCIs.

It can be seen that, in this example, when transmission time of any one of the multiple DCIs is after the transmission time of the first DCI, all the feedback response information is uniformly processed to avoid increasing implementation complexity caused by using different multiplexing manners for different feedback response information.

In a possible example, the method further includes: receiving, by the network device, the preset time interval from the terminal; or receiving, by the network device, information of terminal capability from the terminal, the information of terminal capability including the preset time interval.

In accordance with the implementation as shown in FIG. 2 and FIG. 3, now referring to FIG. 4A, which illustrates a method for transmitting information according to an implementation of the disclosure. The method is applied to the above exemplary communication system and includes following actions.

In block 401, the network device transmits a first downlink control information (DCI), the first DCI being used for scheduling the terminal to transmit uplink data in a target time unit through a physical uplink shared channel (PUSCH).

In block 402, the terminal receives the first downlink control information (DCI), the first DCI being used for scheduling the terminal to transmit uplink data in a target time unit through a physical uplink shared channel (PUSCH).

In block 403, the network device transmits a second DCI, feedback response information of the second DCI being transmitted in the target time unit, and transmission time of the second DCI being before the target time unit or the same as the target time unit.

In block 404, the terminal receives the second DCI, feedback response information of the second DCI being transmitted in the target time unit, and transmission time of the second DCI being before the target time unit or the same as the target time unit.

In block 405, the terminal determines, according to the transmission time of the second DCI, to transmit the feedback response information of the second DCI through the PUSCH in the target time unit.

In block 406, the network device determines, according to the transmission time of the second DCI, to receive the feedback response information of the second DCI through the PUSCH in the target time unit.

It can be seen that, in this implementation of the disclosure, the network firstly transmits the first DCI, which is used for scheduling the terminal to transmit uplink data through PUSCH in the target time unit; secondly, transmits the second DCI, feedback response information of which is transmitted in the target time unit, and transmission time of which is before or the same as the target time unit; and finally determines, according to the transmission time of the second DCI, to receive the feedback response information of the second DCI through PUSCH in the target time unit. The transmission time of the second DCI can be used for determining the feedback response information and the PUSCH multiplex transmission, so as to accurately multiplex and transmit the feedback response information through the PUSCH, thereby avoiding such a situation that the network device cannot perform accurate data scheduling as being unable to accurately identify information (such as number) of the feedback response information, and improving the accuracy and stability of data scheduling in the communication system.

The implementation of the disclosure are further described below in conjunction with specific application scenarios.

As shown in FIG. 4B, assuming that the terminal is a smart phone, the network device is a base station (gNB) in the 5G NR communication system, and the time unit is a time slot. The gNB transmits the first DCI to the terminal in the time slot n, and the first DCI is used for scheduling the uplink data to be transmitted in the time slot n+k through PUSCH. The gNB transmits the second DCI1 to the terminal in the time slot m1, the second DCI1 is used for downlink scheduling and its corresponding feedback response information is the ACK/NACK information. The gNB transmits the second DCI2 to the terminal in the time slot m2, the second DCI2 is used for downlink scheduling and its corresponding feedback response information is ACK/NACK information. The feedback response information of both the second DCI1 and the second DCI2 are transmitted through PUSCH in the slot n+k. After receiving the first DCI, the second DCI1, and the second DCI2, the terminal determines that the time slot m1 of the second DCI1 is before the time slot n of the first DCI and, thus, performs rate matching on the uplink data scheduled by the first DCI according to the number of bits of the feedback response information of the second DCI or the resource occupied by the feedback response information of the second DCI1. Moreover, the terminal determines that the time slot m2 of the second DCI2 is after the time slot n of the first DCI and, thus, transmits the feedback response information of the second DCI1 and the uplink data being rate matched through said PUSCH, and multiplexes the feedback response information of the second DCI into said PUSCH in a puncturing manner for transmission.

As shown in FIG. 4C, assuming that the terminal is a smart phone, the network device is a base station (gNB) in the 5G NR communication system, and the time unit is a time slot. The gNB transmits the first DCI to the terminal in the time slot n, and the first DCI is used for scheduling the uplink data to be transmitted in the time slot n+k through PUSCH.
